Omni A & AB Tank

The Omni Tanker A & AB tanks are dangerous goods rated tanks for highly corrosive chemicals. These tanks are mounted to road trucks or trailers along with a specialised dangerous goods fit out, and used as road transport tankers.

The tanks can be mounted to a rigid truck chassis or skeletal trailer in many different configurations based on customer requirements. The largest combination of Omni Tankers used in Australia is a B-Double tanker, referred to as a B-Train in many countries, with a total volume of 40,000 litres across three tanks. The tanks are type approved according to Australian Standard 2809 “Road Tank Vehicles for Dangerous Goods”.

The tank volumes range from 12,600 to 15,000 litres. Greater overall transport volumes can be achieved through the use of multiple tanks on a trailer or through custom tank designs. Generally, the tanks contain two separate sealed compartments, each at half of the aforementioned total tank volume, to comply with maximum allowable small compartment tank volume based on Australian standards.

The tanks are suitable for transporting highly corrosive chemicals such as sodium hypochlorite, hydrochloric acid, sulphuric acid, ferric chloride, ferrous chloride, caustic soda, and many others, without degradation of the liner.

The patented Omni Tanker thermoplastic liner is specifically designed to provide high chemical resistance to composite tanks and a marked improvement on standard lining techniques. The lining technology overcomes problems associated with bonding thermoplastics to thermoset composites, with bond strengths similar to epoxy to steel adhesion having been demonstrated.

The Omni Tanker A and AB tanks are game changing technology for transport operators. This has been recognised by JEC, the largest composites industry network worldwide, who awarded the tanks the 2016 JEC Americas Innovation Award (Transport Category).

The combination of the lightweight carbon fibre composite structure, and a highly effective thermoplastic liner, results in major benefits to transport operators. See our Benefits to Operators section for more information.

Benefits to Operators

The Omni Tanker A and AB tanks are composite tanks that combine lightweight, very high chemical resistance, and a competitive selling price, to result in major operating cost reductions and profit increases to transport operators. Read on for more information.

Lightweight Composite Technology

The tanks were designed with the need for lightweight in mind, and weigh approximately half the mass of an equivalent volume steel tank. This is attributed to the carbon fibre composite technology used in construction.


The first and most commonly understood benefit of the tanks being lightweight is that there is reduced fuel consumption per litre of payload transported, leading to fuel savings and reduced emissions associated with transport.


The second benefit, which is less known but potentially much greater, is that there is increased payload that can be transported in a single run on the road, owing to a government mandated limitation of total mass on the road of the truck, trailer, tanks and payload. This increased payload is highly beneficial, as transport of dangerous corrosive chemicals is done at a premium rate per litre of liquid cargo, resulting in significantly higher company profits.


The third benefit is that the wall construction of the tanks results in a highly effective insulation layer for the chemicals during transport. Many corrosive chemicals partially breakdown during transport, and the rate of breakdown increases with temperature. The insulation reduces breakdown as the outside ambient temperature rises on long hauls.

High Chemical Resistance

The tanks having excellent chemical resistance by design, which enables a number of benefits to transport operators. This resistance comes about through the use of the patented Omni Tanker thermoplastic liner.

Benefit 1: High Chemical Resistance

Many corrosive liquid dangerous goods that were previously only transportable in lined steel tanks, or extremely high cost tanks made from exotic metallic materials such as Incoloy, can now be transported in lightweight composite tanks with high confidence.

Benefit 2: Longer Life and Low Maintenance

The liners and therefore the tanks have greater durability, longer life, lower maintenance costs and higher purity of transported product compared to standard liners. Standard liners used for dangerous goods transport, including rubber coated steel and thermoset polymer reinforced with glass chopped strand mat, tend to breakdown over time resulting in a need for high cost refurbishment involving scraping out the old liner and replacing it. When transporting chemicals such as sodium hypochlorite, the breakdown time is typically three to six year.

Furthermore, towards the end of the life of standard liners, the breakdown of the liner materials results in product contamination. Omni Tanker liners do not break down in the harshest of chemicals resulting in low maintenance tanks that can transport high purity chemicals continually without contamination.

Benefit 3: Better Asset Utilisation Through Backloading

The liner material allows high utilisation of tank assets, and flexibility far exceeding that of standard liners. This is because the thermoplastic Omni Tanker liner does not absorb chemicals, which in turn permits very effective washout and cleaning, allowing the chemical transport cargo to be changed easily. The chemicals can be incompatible liquid cargoes such as hydrochloric acid and sodium hypochlorite. Standard liners absorb the chemicals that they carry, and often become dedicated assets for transporting a single type of chemical.

This washout and cargo change capability permits transporters to do what is known as back-loading, where the tank transports a certain chemical from point-to-point in one direction, and then, rather than the tank returning to the first point empty, it is washed out and filled with a different chemical for the return trip. The tank assets can also be utilised in high seasonal demand periods for one type of chemical.
